Resource Evaluation

Surface water• Restricted Allocation Areas – restrict availability of new surface

water• Minimal projected demand for new surface water through

2035

Groundwater• Updated LKB groundwater model to evaluate:

2035 projected demands Drawdown potential under MFL lakes

• No adverse impacts projected to SFWMD or SWFWMD MFL lakes

10

2014 Future Direction

Complete development of Kissimmee River Basin Water ReservationCoordinate with SWFWMD to refine modeling of LKB region

and MFL lakesUSACE complete HHD rehabilitation and revise the

regulation scheduleContinue to implement MFL recovery and prevention

strategiesWater users and SFWMD collaborate to increase

understanding of the aquifersContinue to promote water conservation opportunities

within the planning area

11

2014 Lower Kissimmee BasinWater Supply Plan Conclusion

The future water demands of the region can be met through the 2035 planning horizon with appropriate management and continued development of available groundwater sourcesAdditional water from Lake

Okeechobee from operational flexibility within the existing LORS08 schedule, or a revised regulation schedule subsequent to HHD repairs could return the Lake to an MFL prevention status, enhance existing permitted users level of service and support environmental needs

Statutory Goal of LKB Water Supply Plan

Section 373.709, Florida Statutes

To identify sufficient water supply sources and future projects to meet existing and future reasonable-beneficial uses during 1-in-10 year drought conditions through 2040

while sustaining water resources and related natural systems.

18

Objectives of 2019 LKB Plan Update

1. Water Supply: Identify sufficient sources of water to meet reasonable-beneficial uses projected through 2040 under 1-in-10 year drought conditions without causing harm to natural resources

2. Natural Systems: Protect and enhance environmental systems, including the Kissimmee River, Lake Istokpoga, Fisheating Creek, Taylor Creek, Nubbin Slough, and other federal, state, and locally identified natural resource areas

3. Conservation: Encourage water conservation measures to improve the efficiency of existing and future water use

19

Objectives of 2019 LKB Plan Update

4. Linkage with Local Governments: Provide information to support local government comprehensive plans. Promote compatibility of the plan update with tribal and local government land use decisions

5. Compatibility and Linkage with Other Efforts: Promote compatibility and integration with the following planning-related activities: • Other state and federal water resource initiatives in the planning

region;• Existing and proposed environmental projects;• Modifications to operating schedules for the regional systems,

including Lake Okeechobee; and• Water use permitting process, Minimum Flow and Minimum

Water Level (MFL) criteria, and Water Reservations

Purpose: Reevaluate and define operations for the Lake Okeechobee regulation schedule that take into

account nearly complete additional infrastructure, such as C-44 and C-43, which will soon be operational components of the water management system.

Potential Benefits: Manual will result in a new water management schedule that addresses the congressionally

authorized purposes that include flood risk management; water supply for agricultural irrigation, municipalities and industry, environment, and Native American Tribes; navigation; enhancement of fish and wildlife; and recreation.

Data Sources for Agricultural Projections

36

Statutory Basis for Projections

2013 legislation (Section 570.93, Florida Statutes) requires FDACS to develop statewide agricultural demand projections

• Acreage – historical, current, and 20-year projection, by crop

• Demands for average rainfall and 1-in-10 year drought, by crop

• Metered data factored into estimates of historical and current demands

• Consult with stakeholdersFDACS now publishes the annual FSAID

report

37

Statutory Basis for Projections

Section 373.709, Florida Statutes: Agricultural demand projections in water management districts’ regional water supply plans should be based on best available data• Must consider data of future demands provided by FDACS• Any deviation from data must be described• FDACS data are presented with adjusted data

AFSIRS FSAID

Built with data from University of Florida field experiments

Built with available reported water use from all water management districts

Uses a wide range of location-specific environmental variables

A limited set of environmental variables are used directly in the model

Does not consider changing irrigation intensities in response to crop profitability

Irrigation intensities vary in response to crop profitability

Use of AFSIRS in 2019 LKB Plan Update

AFSIRS model is similar to the model used to establish water use permit allocations in the regionAFSIRS estimates are consistent with previous planning

efforts for the LKB and other planning areasUnique aspects of agricultural production in the LKB may

be under-represented with statewide FSAID model
